        abstract = {Mathematical representation skill is one of the goals in mathematical instruction especially in high school as well as college. Multiple representation skill is the ability to present a mathematical object (problem, statement, solution, model, etc) into a variety of notation that include (1) symbolic (algebraic form and formula); it is used in manipulating, interpreting, and operating with symbols, (2) visual: to interpret , to create, and to operate mathematical object in graph or images, (3) numerical: this is used to apply the procedure, to understand and implement the process, and to interpret the table. This study examined the effect of problem based learning in representation skills of high school students.  Experimental design with pretest-posttest was applied to obtain the effect with involving 42 high school students who were studying at the third grade. Multiple representations of mathematical tests were designed to get the data. Quantitative and qualitative methods were applied to analyze the data. The result shows that problem based learning is effective to enhance representation skill of students.
